This is the term used when someone does not get out of the way of a fire truck in route to a call.
A firefighter is driving to the scene of a fire. The person in front of him does not move when seeing the lights and hearing the siren. As you pass the driver of the vehicle looks to you as if there is something wrong. You look back and say Duh! BIG RED TRUCK
